[cups.development] Duplex and Tumble issue, bad colors

[Aurélien Croc]

Hi, 
I'm the main developer of the QPDL (SPL2, SPLc) driver (for most of the 
Samsung ans several Xerox and Dell printers).

I recently added the support of the color printers. To do my job, i use this 
configuration:
*ColorModel CMYK/Color: "<</cupsColorSpace 6/cupsColorOrder 1/cupsCompression 
17>>setpagedevice"

This QPDL language is just a compressed bitmap language. Some of the users 
report to me some troubles with colours in particular during the print of 
pictures.
I'm pretty sure that there is some troubles during the conversion of colours 
with ghostscript..

Another important thing is about the Duplex and Tumble support. I use 
the "Duplex normal" comand in the driver file which generate a good code for 
Duplex support in PPD files. Unfortunately, the fields Duplex and Tumble in 
the raster header are always set to 0...
I don't understand what's wrong with it.
